Application filed April 20, 1911, Serial No. 622,390. Benewed April 8, 1914. Serial No. 829,379.v

To all whom it may concern Be it known that I, BENJAMIN D. CHAM- BERLIN, a citizen of the United States of America, and a resident of Corning, New York, have invented certain new and useful Improvements in Mechanism for Gathering Glass, of which the following is a specification.

In the prior application filed by me on the- 23rd day of March 1910, Serial No. 551,198,

I have disclosed a machine in which an iron is presented to and inserted in a furnace mouth and then dipped into the glass from which a gather is to be made. y

My present invention comprises means by which the extent to which the iron is dipped.

is controlled by the level of the glass itself so that as the level is lowered in using from it the iron successively follows it down in dipping. For this purpose I provide a dip regulator, which itself is controlled by the level of the glass and-to which the gathering machine surrenders the control -of the iron temporarily while the gather is being of fected. In this aspect my invention is ca- -I pable of numerous embodiments, and it further consists in the construction, arrangement and combination of. several parts which constitute the embodiment which is herein shown as an example of my broad 1nvention.

Referring to the accompanying drawings in which corresponding parts are designated by corresponding marks of reference Figure 1 is a fragmental vertical section through the furnace and machineembodying my invention. Fig. 2is a plan view thereof partly in section. Fig. 3 is a fragmental front elevation of mechanism attached to.' the furnace. Fig. 4 is a fragmental plan view of.

the gather iron and its controlling arnr,

The gathering machine shown inthe accompanying drawings is of the general type disclosed in my prior application #551,198 hereinbefore referred to and comprises a frame rotating in the direction of the arrow (Fig. 2) around a vertical axis and having a series of radially disposed arms 2 projecting from the periphery thereof, in each of which arms is pivoted by. a vertical axis a.

frame 3 carrying in its outer end the horizontal trunnion 3 of the support 3 ofthe gather iron 3. The rotation of the frame and the movement of the pivoted arms thereon will bring the several irons carried thereby successively ast them'outh ofthe furnace 4, and willi insert and withdraw the pipes in and from the-furnace r .outh and also maintain them there for a time sufiicient to permitthegather to be efi'ected.- 1 Inasmuch as the mechanism for accomplishing these movementsv of gatheriron forms no part of this invention it need. not be described herein. The movement of'the gather iron'support allowed bv its horizontal trunnion, when the end of the blow-pipeis inserted in the furnace, provides for the dipping of the iron into-the glass from which the gather is to befmade. In my said rior application thismovement of the get er iron on its horizontal axis for thispurpose and for other purposes is effected by appropriate gearing controlled by a fixed cam disk and is always due to the shape of the cam run therein. I In my present invention I still retain the'ca-m run for accomplishing the vertical motion of the iron other than that actually gathering, but for this latter purpose, cut away a portion of the cam run so that the iron'at the gatherin under-the control thereo drawings in myprior application the general vertical control of the iron is effected by a fixed cam disk 5 which by its cam run 5 controls the movement of the radial slide bars 6 and throu h the gear wheels 6, 6 and 6 and bevele. gears 6", 6, 6 and 6 the latter of which is fixed upon the rear end of the trunnion 3 of the blow-pipe. I however for the purposes of this invention cut away a portion 5" of the cam run 5 at that Wall thereof which arrests or controls the lowering of the blow-pipe, at the point which should control the radial movement of each slide bar during thetime the gather iron of that unit is inserted in the furnace. Thus during the gathering the gathering machine has no function other than to form a pivot upon which the gather iron is moved to effect the gather and to provide for the rotation of the iron around its longitudinal axis. This latter is accomplished by mechanism similar to that of my prior application. The furnace 4 is adapted to cooperate with the mechanism before described and has therein the usual pot 4 containing rests the inner end of an arm 8, Which pr0-' jects outwardly through the upper part of the mouth of the furnace and is pivoted intermediate of its length at 8 in the upper part of such opening to a bracket casting 9 fastened to the outside Wall of the furnace.-.

The opposite end of this lever extends upwardly-uncles connectedby the outwardly extending adjustable slotted. link l0- to the medial portion of thelever ll, the upper end of which is pivoted at 11* to the bracket casting. The lovver end of the lever carries a cross bar or track 12 upon face. the' ends of which are beveled as at 12 and which is properly shaped to maintain a roper dipping of the iron inthe molten glass during the periodnecessary to effect the gather. l his control by the her of iron is provided for by securing to the iron supporttl a rearvvardly extending arm it carrying a roller 13 in its end, which roller, when the gather endof the iron-is in the furnace,

gather end ofthe iron at such timeloeing above an opening'l formed in 'the'float Z.

' As thus constriicted',- when an iron carried tih till

by the main framers projected into the furnace month by themovementoft-he former and of the arm 2 in relation thereto, the radial slide bar- 6 corresponding to such arm will be opposite the cutaway portion 5 'ofthe cam run 5 and the machine will thus lose control of the iron in so far as re lates to the elevation of-thegathering end thereof. Such end of the iron wih thus drop until arrested by contact between the roller 13 carried on its's'upportand the track formed by the bar 1% attached to the furnace. The elevation of the gather end of the iron is now controlled by the har and will depend upon the'contour given the same and to its angular position around its pivotal point 11?. 'l he latter of these is automatically regulated by the level of the glass in the pot by the mechanism which has been described, the lowering of the level causing the descent of the float and the corresponding in'w ard movement of the bar 12. The leverages between the float and the bar and between the end of the gathering iron and the roller 18 on the arm 13 thereof are such that the elevation, of the gathering end of the iron will be varied in successive gathers precisely in the same rate that-the level of the glass varies and thus a uniform immersion of the iron in successive gathers Will be maintained. The continued motion of the main frame will, after elapse of a proper time to properly efl'ect'the gather bring the radial slide bar of the gathering iron into contact with the curve which terminates the cut awayportion 5 of the cam its forward will lie under 'thetraclr-"- 1'2, the

run, and the machine again assumes control of the elevation of the iron, raising the end thereof to permit the Withdrawal of the same from the furnace mouth.

Having thus described my invention What claim and desire to secure by Letters Pat 2. The combination with means for inserting a gathering device in a furnace, Withdrawing it therefrom and for varying the elevation the gathering end of the blowpipe when WlthdIELWIl,-Of means controlled by the elevation of glass in the furnace for regulating the dipping of the device when in the, furnace. I

3. The combination with a mechanism adapted to insert a gathering device into a furnace and to Withdraw it therefrom and to aflord a support for the device "when in the furnace, of means controlled by the level of glass in the furnace from varying the inclination of the device upon its support.

4:. The combination with a pivotal mounting for the gathering device, of a gathering device mounted thereon and rojecting with in the furnace, a float Wit in the furnace and mechanism for shifting the gathering device upon its pivot by avariation of level of the float. i
